Sadly, we have moved indoors and away from nature. Part of living a healthy lifestyle is enjoying the outside world. Unfortunately, for most people it has become unnatural to go outside for an extended time-period.

Here's what you will discover if you go outside for a walk, a hike, or a run. It's great exercise and it is incredibly therapeutic.

Now that I have watched all four parts of HBO's documentary, I would recommend watching the last segment. The main reason: It's mostly about food.

As I have stated before: We do not have an obesity epidemic. We have a food crisis.

Here are just a few observations about the documentary.

There's a heavy concentration about eating fruits and vegetables. Everyone already knows to do that. Here's the real problem that is not addressed: How do you prepare and cook fruits and vegetables into delicious meals? Ironically, it is not difficult. Here are two simple examples - a fruit smoothie and an amazing veggie dish.

Throughout the documentary they stress community involvement, however, there's no serious attempt at a social networking component. For example, a reason to join an ongoing Facebook community or petitions at Change.org for better school lunches, elimination of food deserts, and more.

The documentary obsessed about diabetes, however, there was rarely a mention of heart disease.

On several occasions, they mentioned that children might die at a younger age than their parents (paraphrasing). I have a sneaking suspicion that over the next 50+ years, medical technology will keep us alive for a long time. It's already happening.

This is a 7-part documentary on the subject. You may be familiar with Dr. Robert Lustig. He's a YouTube "star". This video, Sugar: The Bitter Truth has been viewed over 2-million times. He has also been seen on a recent 60 Minutes segment: Is Sugar Toxic?

An Epidemic for Every Body - How did we get so fat, so fast? The debut episode debunks the theory that obesity only affects the “gluttons and sloths” among us and is, in fact, a public health problem that impacts everyone.

Sickeningly Sweet - Dr. Lustig illustrates the overabundance of sugar in today’s processed convenience foods and explains how our bodies metabolize these sugars in the same way as alcohol or other toxins, causing damage to the liver and other organs.

Hunger and Hormones: A Vicious Cycle - Sugar impacts the brain just as much as the waistline. In this episode, Dr. Lustig explains the biochemical shifts that sugar causes, making us store fat and feel hungry at the same time.

Sugar: A Sweet Addiction - Sugar isn’t just sweet, it’s addictive. This episode explores the cycle of addiction that sugar causes in the brain, much in the same way as drugs and alcohol.

Generation XL - An unnerving trend of obese infants is just one indication that obesity can be passed on from mother to fetus. This installment looks towards the next generation, with an emphasis on preventive care and pre-natal health.

A Fast-Paced, Fast Food Life - The pace of modern life is a key contributor to today’s obesity epidemic. Elissa Epel and Barbara Laraia explain the connection and offer practical and effective solutions that don’t involve dieting and exercise.

Drugs, Cigarettes, Alcohol…and Sugar? - Our experts offer a frank indictment of the country’s agricultural policy and food industry, which have made it nearly impossible to avoid sugar in our daily diet, and suggestions for possible remedies.

In this illuminating article (A Mathematical Challenge to Obesity), Dr. Carson Chow explains how we got to be an obese nation. The one answer he provides below pretty much explains it.

Q. Did you ever solve the question posed to you when you were first hired — what caused the obesity epidemic?

A. We think so. And it’s something very simple, very obvious, something that few want to hear: The epidemic was caused by the overproduction of food in the United States.

Beginning in the 1970s, there was a change in national agricultural policy. Instead of the government paying farmers not to engage in full production, as was the practice, they were encouraged to grow as much food as they could. At the same time, technological changes and the “green revolution” made our farms much more productive. The price of food plummeted, while the number of calories available to the average American grew by about 1,000 a day.

Well, what do people do when there is extra food around? They eat it! This, of course, is a tremendously controversial idea. However, the model shows that increase in food more than explains the increase in weight.

That's the title of this song by Loudon Wainwright. The song is hysterical, but sadly, if you eat the Standard American Diet, you can assume you will be on some of the meds Mr. Wainwright sings about.

After viewing this video, I decided to acquire this domain: NoAchesNoPainsNoMedsNoDocs.com. A choice can be made: Live a healthier lifestyle and avoid most of the chronic diseases that this diet causes.

While the song is funny, the implications of living in the Circle of Disease are not.

Now enjoy this funny song.

While Loudon Wainwright's song is hysterical, I prefer Bill Maher's rant about big-Pharma.

A policeman sees a drunk man searching for something under a street light and asks what the drunk has lost. He says he lost his keys and they both look under the streetlight together.

After a few minutes the policeman asks if he is sure he lost them here, and the drunk replies, no, that he lost them in the park. The policeman asks whey he is searching here, and the drunk replies, "this is where the light is."

In this country we are obsessed with obesity. As the article states: we have an obesity epidemic. HBO (Weight of the Nation) states: Obesity in America has reached a catastrophic level.

In reality, we do not have an obesity epidemic. Actually, the catastrophe and epidemic is the food. By focusing on obesity and not the food, we have taken the wrong fork in the road. The question we must ask is: "What is the cause and effect?" From my perspective, we can draw a direct line from our horrific food environment to disease. Unfortunately, because it takes many years to experience the negative effects of eating the Standard American Diet (SAD), we concentrate on obesity.

However, when it comes to food, it's a little more complex. We crave salt, sugar, and fat. Over the past fifty years, our Main Street has been littered with those ingredients. To compound the problem, food manufacturers have fed the monster by adding a tremendous amount of salt, sugar, fat, and poison to our foods. To demonstrate, a recent M&M's commercial stated: "Salty. Sweet. Impossible to resist." Yes, in fact, these foods are impossible to resist. And, many of us are addicted to these over-the-top foods.

One important thing to note: If we changed our lifestyle - stop smoking, eat better, and exercise - upwards of 90% of type 2 diabetes, 80% of heart disease, and 60% of the cancers would disappear. One other thing would go away too: our health care dilemma.

The heavy concentration on the obesity epidemic reminds me of the Street Light parable. So, next time the obesity issue raises its ugly head, let's think in terms of the food.

I recommend reading this observation from a doctor who works with obese patients. He hits the nail on the head.
